Jeti specbos 1211-2 Broadband Spectroradiometer

The Jeti specbos 1211-2 is a miniaturized and fast broadband spectroradiometer covering the wavelength range from 350 ~ 1000nm. It can be used for various applications both in lab as well as in production and can measure in Radiance and in Irradiance mode based on its NIST traceable calibration. Includes 90° diffusor to allow Irradiance measurements perpendicular to the instrument.
